PGLYRP1 and Immunodeficiency: Further inspection of the results produced a list of the most strongly regulated genes encoding D. melanogaster proteins with immune properties [e.g., members of the immune deficiency Imd pathway such as Relish, the antimicrobial peptides Attacin, Diptericin, Drosomycin, Metchnikowin, recognition proteins such as Peptidoglycan Recognition Proteins (PGRP) and Gram-Negative Binding Proteins (GNBP) as well as various immune-induced proteins and thioester containing proteins] [29].
